Programmable with the included Castle Link USB adapter - the Castle Link software suite offers industry leading software functions and programming capability as well as access to all firmware updates and new features at no cost!

Throttle Calibration and Motor Direction can be easily set in the field Two versions - one with a low noise 5.6V 5A switching Battery Eliminator Circuit (BEC) and one with no BEC to reduce weight

This pack of four (4) 35 amp ESCs has already been optimized for use in your Quadcopter or Multi-Rotor by utilizing three (3) ESCs without a BEC and one (1) with a BEC. No more hassling with disabling the BEC on three of the ESC, this package is made specifically to save you the headache. The small footprint and lightweight design makes it the perfect choice for smaller Quads and Multi-Rotors.

V5 firmware now supports 4Khz including OneShot 125 for faster signaling and improved stability during all aspects of flight from a simple hover to the most extreme maneuvers.

QuadPack 35 comes preprogrammed for Multi-Rotor platforms and is recommended for platforms ranging from 450 to 650 sizes pulling up to 35 amps** and running up to 6S LiPo. As with all Castle ESCs, this product is easily programmable using the Castle Link USB adapter.

Access to all firmware updates, including added features sets released from Castle Engineering, at no charge.

1Specification only applies to the Multi-Rotor 35 w/BEC units.

2Specification only applies to the Multi-Rotor 35 “NO BEC” units. “NO BEC” units require a BEC supply voltage in order to operate. It is recommended to use the supply from a Multi-Rotor 35 “w/BEC” unit to power Multi-Rotor 35 “NO BEC” units.

3Current is specified as the maximum value the ESC can handle at full throttle for the duration of a single 4,000 mAh battery pack with the ESC in the specified speed of 25°C (77°F) or cooler airflow. Controller temperature must never exceed 100°C (212°F). Exceeding current or temperature ratings may damage components and may shorten the life of the ESC. Always verify system current draw at full-throttle. Decrease load or increase airflow to decrease the ESC’s operating temperature.
